Comment (by bgamari):

 Very interesting...

 `$lr` falls on this relocation,
 {{{
 Rel entry  49 is raw( 0x21c 0x461c)lookupSymbol: looking up
 foreignExportStablePtr
 lookupSymbol: value of foreignExportStablePtr is 0x3ece80c
 `foreignExportStablePtr' resolves to 0x3ece80c
 Reloc: P = 0xb6ff7224   S = 0x3ece80c   A = 0xebfffffe
 }}}

 Which happens to be the last relocation of the `.text` section of
 `Test.o`,
 {{{
 RELOCATION RECORDS FOR [.text]:
 OFFSET   TYPE              VALUE
 ...
 00000218 R_ARM_MOVT_ABS    Test_zdfstableZZC0ZZCmainZZCTestZZCf_closure
 0000021c R_ARM_CALL        foreignExportStablePtr
 }}}

 Might this be causal?
